Unfavourable results: their causes. — The results 62' 

 however of this season were unfavourable, both as re- 

 garded the crop and the proportion of wool Dr. Wight's 

 to seed. Dr. Wight ascribed the failtire to jj^^^er** 

 two causes : — 1st, To the circumstance that ism. ibid. 'p. 

 the abundance of rain brought by the north- ®^^' 

 east monsoon had fallen within too short a period, and 

 had been followed by a long period of dry weather ; and 

 2nd, To the American system of ridging, which created 

 a deep water furrow on each side of the row of plants, 

 and thus in dry seasons drained the water too rapidly 

 off the lands. This latter idea had already been made 

 the suWect of experiment. At an early 

 period Dr, Wight had not considered that ^ ^'"^'^ 

 American ridging was suitable to an Indian climate. 

 Accordingly during the second year he had tried the 

 effect of sowing on level ground ; but then the season 

 had been unusually wet, and the ridging would have 

 served to carry off the water. In the third year he 

 had reverted to the ridging ; but then the season had 

 turned out unusually dry, and the ridging drained the 

 land too rapidly, and in fact proved worse than the 

 level method. The real cause of the failure appears to 

 have been the exhaustion of the soil, and the necessity 

 for a rotation of crops. However this subject will be 

 discussed further on.
